Lawrence,

I am working on some weather modules for the VSCP (http://www.vscp.org)
project of mine. Don't now if they ever will be finished but it's fun to
work with... I will post the stuff I developed on the mentioned site
with the first being a temperature & Humidity module. I use the SH11
http://www.sensirion.com/humidity for this module with a 18F258.

For wind speed there is an interesting kit from kitsrus (
http://www.kitsrus.com/pdf/k168.pdf ) using Ultrasonic. Interesting with
something without moving parts.

For pressure you have the Motorola parts. You have some 1-wire stuff
here http://www.simat.enta.net/v3barocal.html that can easily be adopted
for a pic.

For visibility I am looking into some scattering sensors. Should be
doable with a PIC and some IR transmitter/sensors.

I would love to be able to monitor lightning. Some stuff is abailable on
the net but the nicest solution would be to be able to detect distance
as well as a strike.

For rain AAG have some solutions. I think its hard to come up with a
solution here that is without moving parts.

The simplest and possibly the most low cost solution is to use 1-wire
and the weather station from AAG http://www.aagelectronica.com . Maybe
letting a PIC do the 1-wire part.

Anybody done a weather station with a PIC?

What did you use for a barometric pressure sensor?  Wind speed sensor?

Of course there are some stock sensors that come to mind (motorola?)
mostly targeted at the industrial lab market ($$$).  I am looking for
low
cost consumer solutions that have already been tried.
